is disabled, no trace output will be provided, and the module will disable (drive inactive) auxiliary port
output pins MDO[n:0], MSEO[1:0], MCKO. Nexus registers will not be available for reads or writes.
24.10.6 TCODEs Supported by NZ6C3
The Nexus3 pins allow for flexible transfer operations via public messages. A TCODE defines the transfer
format, the number and/or size of the packets to be transferred, and the purpose of each packet. The
IEEE
®
-ISTO 5001-2003 standard defines a set of public messages. The NZ6C3 module supports the
public TCODEs seen in
. Each message contains multiple packets transmitted in the order
shown in the table.
